ACPI is Advanced Configuration and Power Interface.
Firmware provides tables that supply the values and parameters for the kernel to know what is needed for the drivers for that hardware.
It is not unusual that hardware manufacturers use rather generic values, guess at values or just copy and paste old values into a list rather than go to the trouble of looking them up.
The Linux kernel is adaptable and when a value has a mismatch, you can see a warning like that. The kernel then falls back to known values in order to init the hardware.
If you want to, you can silence the annoyance by adding the loglevel=3 grub parameter.
You can search the forum to learn more information about ACPI warnings.
As for a detailed breakdown of what your specific warnings are referring to and what the cause is:
I couldn't tell ya. Those ones look about as generic as they can get.
Sometimes, as @applecheeks37 pointed out, a BIOS firmware update can resolve some of them.
